Sizes 2-20

Sizes 18-34

The Mary Sun Hat comes in one size and the ribbon ties make it adjustable for a personalized fit. The finished flat width of the hat is 19-1/4 inches (48.9 cm).

Recommended Fabrics

We recommend light- to medium-weight wovens: cottons like sateen, poplin, broadcloth, shirting, chambray, and quilling cotton; linen and linen blends; and silks such as taffeta, dupioni, and shantung.

Notions & Supplies

• Fabric for the hat
• Ultra-firm heavyweight fusible interfacing
• Thread to match
• Two decorative snaps (sizes 16-20)
• 1-1/2 yards (1.4 m) of 7/8-inch-wide (2.2 cm) ribbon for the ties
• 2 yards (1.8 m) of 1/4-inch-wide (6 mm) double-fold bias tape (or make your own using a bias tape maker

• 1/2 yard (0.5 m) or one fat quarter of the main fabric
• 1/2 yard (0.5 m) or one fat quarter of the contrast fabric
• 1 yard (0.9 m) of 20-inch-wide (0.5 m) ultra-firm heavyweight fusible interfacing

Measure yourself around your upper bust (under your armpits and above your breasts, without a bra on), the fullest part of your bust (while wearing your preferred bra), the smallest part of your waist, and the fullest part of your hips (this is likely around the fullest part of your butt). Make sure to hold the measuring tape snugly and parallel to the ground. Compare your body measurements to the size chart.

Find your upper bust measurement on the size chart to find your garment size, and then scan down the cup sizes in that garment size column to find your cup size. For instance, a 37-inch upper bust will make you a size 10, and a 39-inch full bust means you need a B cup. Don’t worry if your waist doesn’t match the size 10 column’s measurement of 32 inches; you can grade the waist in or out as needed. It is most important to choose a size to fit your upper bust and cup size, as the waist is easier to adjust up or down.

Sewing pattern sizes are very different from ready-to-wear garments and bra sizes, so be sure to work with your measurements when choosing a size.

Charm’s 2-20 size range is designed for a body with an hourglass shape. Our 18-34 size range is designed for a body with less waist definition.

It will show you how to choose which PDF format to use, how to print just your size(s), and how to easily assemble and cut out your pattern pieces.

We offer digital patterns in two formats: letter-sized PDFs to print at home and A0 sized PDFs to print at a copy shop. In the US, we highly recommend printing A0 files with The Plotted Pattern. Outside of the US, these printers have been recommended.
